Hi Andy,
If I weren't so deeply in love with my '82 Distillate (and if it weren't so beat up), I'd surely consider your offer. That is quite a stunning Elan. My Distillate certainly has its share of 'battle scars.' Here's a little pic, note the non-original brass plate with red LED indicator.
I also prefer the look of the older Distillates with the shorter upper horn, but mine balances horizontally unless I use the 'Dela Technique for Optimum Neck Support' with my right forearm, which does the trick just fine. Good luck with your trade, I'm sure it will end with 2 happy Alembic owners and a revived passion for the instruments.
Adam
